FIG. 2.
Expression of membrane-anchored T20. PM-1 cells were transduced with the retroviral vectors indicated and selected. The bulk cultures were stained either with a control human monoclonal antibody directed against gp120 (2G12) or with a human monoclonal antibody directed against a sequence within T20 (2F5) followed by a PE-conjugated anti-human IgG goat serum. Shaded curve, PM-1/MPIN; solid line, PM-1 transduced with the vector indicated.
